Well, in terms of advice, relax. Before I interviewed there, I also read up on the interview experiences-some were quite horrid. But if you approach the situation with a positive mindframe, you'll do fine. Get to know your group before the interview, that made the panel format evluation MUCH easier. Dr. Haight is a great guy, keeps a sense of humor but also gives it to you striaght up. Also, when interviewing, don't elaborate too much. TAKE TIME TO THINK ABOUT YOUR ANSWER, don't ramble. A clear, concise answer is much better than a long, elborate one. If staying at the Best Western, get to know other applicants. That's my two cents.
Oh, and best of luck, you'll do fine!
